ことなく廃棄処分されるのが現状である。As can be seen from FIG. 1, in the cloth-applied molded article disclosed in the above-mentioned publication, a fiber sheet is also present in a part of the burrs at the time of molding. Generally, a discarded burr portion in which a fiber sheet or the like is not mixed is reused as it is. However, if the fiber sheet remains, the difference in the specific gravity between the fiber portion and the resin portion causes a variation in the amount of the material to be fed into the extruder, and the amount of extrusion may not be stable. Recycling not only gives rise to the drawback that the fiber mass remains on the surface of the molded article and deteriorates the appearance, but also has the drawback that the physical strength of the molded article is significantly reduced. It is the current situation that discarded burrs and defective moldings are disposed of without being reused.

However, it is extremely difficult in terms of productivity, and despite the fact that plastic recycling has been strongly screamed, the fact is that they must be disposed of.

And that the physical properties and appearance of the molded article do not deteriorate even by reusing the resin material to be reprocessed, and that the thickness of the molded article can be controlled with sufficient accuracy in molding.

得られないという欠点を有している。In general, when the fiber sheet is applied to a thermoplastic resin and crushed by a pulverizer, the fiber sheet is cut into an appropriate size, and a fiber mass of several millimeters to tens of millimeters is obtained. Since the agglomerate fiber and the thermoplastic resin having a lower melting point than the fiber constituting the molded article formed by blow molding have different melting temperatures, when mixed and molded, the fiber is formed on the surface of the molded article. In addition to the appearance, the appearance is deteriorated, and the fiber has a drawback that a desired strength as a molded article cannot be obtained because the fiber basically exists as it is without being melted.

態をとっていると考えられる。In order to make the description concrete, here, polypropylene is used as the thermoplastic resin (A) constituting the molded article, and the thermoplastic resin (B) having a high heat resistance which constitutes the cloth is used.
A case where a polyester resin (polyethylene terephthalate) is used will be described. According to the present invention, first, a molded product or a burr portion on which a cloth is stuck is applied to a pulverizer. At this time, the polyester resin forming the cloth is an aggregate of fibers cut to a certain length, and is mixed with the crushed polypropylene material forming the molded product. Polypropylene, which is a pulverized material constituting the molded article, and a polyester resin in the form of a fiber mass are charged into an extruder, and are maintained at a temperature not lower than the melting point of the polyester resin for a certain time. In this method, the polyester resin having a fiber mass is melted into a resin mass by making the polyester resin have a melting point temperature or higher. Assuming that kneading is not performed with a screw, the molten polyester resin is considered to form a kind of large island in the polypropylene constituting the molded product. In other words, it is considered that the polyester resin is present in a kind of large island shape in the molten sea-like polypropylene.

リプロピレンとポリエステル樹脂との界面にて、極めて
小さな外力で容易に分離するためである。By the way, generally, the polyester resin and the polypropylene resin are basically not mixed because the resins themselves are not compatible with each other. Therefore, in the form in which the polyester resin is present in the form of a large island in the sea-like polypropylene, when it is formed into a molded product, the strength is low. This is because separation can be easily performed with an extremely small external force at the interface between the polypropylene and the polyester resin.

んど影響を与えることがないのである。Therefore, in the present invention, the polyester resin present in the form of large islands is kneaded and extruded by an extruder, thereby micro-dispersing the polyester resin from the large islands into a fine state. Thus, by melt-kneading with an extruder, a large island-shaped polyester resin can be micro-dispersed in a fine state. By doing so, even if separation occurs at the interface between the two, it is very fine, so that the basic physical properties of the polypropylene are hardly affected.

Since the dispersed polyester resin is finely present, the polyester resin can be present as a whole without substantially affecting the basic physical properties of the polypropylene. Therefore, it does not require other compounding agents or fillers for compatibilization, and has the characteristic that it can be simply performed with an existing extruder. The extruder used in the present invention may be a single screw extruder or a twin screw extruder. It is particularly suitable as long as it exhibits kneading properties. As an extruder exhibiting kneading properties, a twin-screw extruder is well known, but even a single-screw extruder such as a flute grooved type Maddox screw, a dalmage type screw, a double flight screw, etc. What used the screw provided in some with a high kneading part is known. In addition, a single-screw extruder, such as a two-stage extruder that changes the screw midway, is also suitable.

れるのであると考えられるのである。The use of the blended resin obtained by the method of the present invention for molding, such as blow molding or injection molding, can be sufficiently carried out using an ordinary molding machine. However, as a matter of course, the molding temperature at this time is, for example, a temperature suitable for molding polypropylene in the case of the above-mentioned polypropylene (generally 170 to 220 ° C.), but at this temperature, the polyester resin does not dissolve. Therefore, in this molding, the polyester resin which is the resin of the cloth remains undissolved as in the conventional molding. Thus, even in the case of the present invention, whether or not the polyester resin of the present invention obtains good results despite the fact that the polyester resin is not dissolved as in the conventional example, in a state where the polyester resin is in a fine micro-dispersed state It is thought to be due to the existence. When the fiber mass polyester resin is melted and dispersed by an extruder, the fiber mass polyester resin becomes finer, so even if it is in an undissolved state, it acts like a kind of filler. This contributes to the improvement of rigidity. Fillers such as mica and talc, when a certain amount is injected into the thermoplastic resin,
It is known to improve physical properties such as rigidity of a molded article made of the thermoplastic resin. This kind of filler does not have a molten state in the molten thermoplastic resin. However, it is the result of the extremely fineness of these fillers and the fact that they are dispersed that the molded article is improved in physical properties such as rigidity. The resin constituting the fiber according to the present invention, the polyester resin in the above example, is not in any way melted in the molten resin of polypropylene, but because it is fine and dispersed. It is considered that the rigidity is improved.

とがないからである。Further, in the present invention, the blend resin obtained by melting and dispersing the lump fibers is once granulated and then blended with a regenerated resin such as a virgin resin or a pulverized material containing no lump fibers. The present invention aims at recycling by performing molding such as blow molding, injection molding, and extrusion molding. According to the present invention, when the blended resin is granulated, it can be stably charged into a molding machine for performing the above-mentioned various molding methods. This is because the granulated blended resin is similar in terms of the bulk specific gravity of the virgin resin, so that there is no variation when it is put into a molding machine.
